5 NOTICE As this catalogue is not intended to cover all of LIBAN CABLES S A L possibilities in Copper Telephone Cables manufacturing, the hereafter listing of the types of cables is not restrictive but only indicative of the main and most current types we manufacture. On the other hand, our specification sheets are inspired mainly from International Electrotechnical Commission Specifications (IEC) only in order to conform with the sustained trend, noticed both regionally and worldwide, towards these same IEC supposed to inspire any further standardization approaches. That is why, while consulting this brochure, it is important to keep in mind that: - any combination or change of the constructional details mentioned in hereafter chapter remains feasible, on base of special conception development, matching any special or different specifications, - we can offer additional possibilities and alternatives like for example: - Pair, quad, and other basic formations - Unit or concentric stranding - Comparted construction (ex: MIC cables) - our production encompasses all telecom cables of low, high or special mutual capacitance and conductor gauges mm. F i n a l l y, and within our policy of constant improvement, we reserve the right to alter any part of the information contained in this publication without incurring any obligation. In all cases this brochure being only indicatve, and unless expressly agreed upon, it cannot be considered by any mean as contractual document.

6 INTRODUCTION Devoted to the manufacturing of electric and telecom cables, Liban Cables is the first and largest supplier in Lebanon and a leader in the Middle-East region. Liban Cables was founded in 7 by a group of Lebanese industrialists backed up by the technical assistance of two international leading firms : - Les Cables de Lyon - France (became A L C AT E Lafterwards and NEXANS by end ) - Phelps Dodge - U.S.A. S t a ffed with qualified engineers and highly skilled technicians, our plant is located in Nahr-Ibrahim at Km from Beirut, where cables are designed and manufactured according to all international specifications : IEC, VDE, UTE, BS and others on customer request. Early after its foundation, Liban Cables has become the major supplier of the Lebanese market in both the public and private sectors. The product range of Liban Cables covers all Copper and Aluminium electric cables, as well as copper and fiber optic communication cables, in addition to a wide variety of special cables manufactured on customer request. High quality cables, continuous developments of the production range, direct and fast shipments have contributed in rendering Liban Cables an important exporter for many countries on the three limitrophe continents (Asia, Europe, Africa). Liban Cables products are particularly appreciated by administrations and international contractors operating in the region and seeking reliable and direct supplies of power and communication cables.

7 QUALITY Step by step, from raw material to final product, quality constitutes a major concern to Liban Cables. Raw material are continuously and repetitively tested from trial orders till the last batch received afterwards. Products are tested within two simultaneous procedures : - A built in quality control system carried out by the production itself at any step of work in process. - A parallel and contradictory procedure is also carried out on the same stages and products by independent inspectors reporting to the quality control service. End users and/or third part inspection authorities are also constantly commissioning the finished products and assessing the strict conformity to ordered specifications. In fact, our ISO certification stated in Feb 7 by the International Certification Network (EQNET) is certified by the French Association for Quality Assurance (AFAQ), the well known rigourous and independant accredited European assessor. T h i s certification, which upgraded to ISO : on February, under reference A FAQ Nº QUAL / 7 / 7 a, confirms the soundness and the performance of the Quality System we apply for the Design, the Development, the Manufacturing and the Marketing & Sales of all our products. RECOMMENDED ORDERING PARAMETERS For prompt quotation / supplies, please make sure your inquiries and your orders are securing the following data : - International or Special Standard. (Alternatively, the precise usage of the cable.) - Constructional details (Materials, Pairs / Quads, Mutual Capacitance, Filling, Screens, Armour, Messenger...etc). - Other requirements - Packing & Tolerances - Required delivery time - Required validity

8 OUR TYPE AND CODE DESIGNATION The type designation is a combination of symbols (letters and numbers) indicating the type, and the main constructional elements of the cable as follows : OUTDOOR CABLES 7 No letter - PE sheath Y - PVC sheath U - Halogen free, Low smoke and fume sheath L - Lead sheath B - Black steel tape armouring G - Galvanized steel tape armouring R - Galvanized round steel wire armouring F - Flat steel wire armouring A- Aluminium tape armouring W - Round aluminium wire armouring Z - One side coated corrugated steel tape K - Two side coated corrugated steel tape S - One side coated aluminium screen D - Two side coated aluminium screen I - Two side coated corrugated aluminium screen Z - Non coated aluminium screen O - Copper tape screen H - Corrugated copper tape screen C - Copper wire screen Q - Lacquered aluminium screen T-Telephone cables P - Solid PE insulation C - Cellular PE insulation M - (Foam / skin) PE insulation Y - PVC insulation - For cables stranded in pairs - For cables stranded in star quads A- Aerial Cables U - Underground / Armoured Cables D - Underground / Duct Cables

9 Example: TUMDG - Telephone cable, underground, pair Type, foam / skin PE insulated, two side coated Aluminium screened, galvanized steel tape armoured. N. B. : The sequence of the rd and th characters indicates whether the cable is jelly filled or not. For jelly filled cables, these two characters are interchanged, i.e. the letter indicating the type of insulation (P,C,M or T) comes before the number indicating the type of stranding ( or ). Examples : TUMDG - Telephone cable, underground, foam / skin PE insulated, pair Type, jelly filled, two side coated Aluminium screened, galvanized steel tape armoured. TUMDG - Same cable but not jelly filled.
